A train that is 1 mile long starts through a tunnel that is also 1 mile long. The train is traveling 15 miles per hour. How long does it take for the train to get completely out of the tunnel?
It will be the time from the beginning for traveling two miles, one mile to get completely in the tunnel and another to get completely out.
2/15 =
To find out how long it takes for the train to get completely out of the tunnel, we need to calculate the time it takes for the train to travel a distance of 2 miles (the length of the train plus the length of the tunnel) at a speed of 15 miles per hour.
To calculate the time, we can use the formula: Time = Distance / Speed.
In this case, the distance is 2 miles (length of the train plus the tunnel) and the speed is 15 miles per hour.
Time = 2 miles / 15 miles per hour.
To solve for time, we divide 2 by 15:
Time = 0.1333 hours.
Since time is usually measured in minutes, we need to convert hours to minutes. There are 60 minutes in one hour, so:
Time in minutes = 0.1333 hours * 60 minutes.
To solve for time in minutes, we multiply 0.1333 by 60:
Time in minutes = 0.1333 * 60 = 8 minutes.
Therefore, it takes 8 minutes for the train to get completely out of the tunnel.
